Subroutine code may be found after the END instruction so it's not always
the last instruction.
At least check for presence of exactly one END instruction though.

cso_set/save/restore_framebuffer()
Fixes asst problems with FBO / render to texture.

KIL takes 1 src register. KILP uses no registers (uses cond codes).

TGSI shaders are translated into SPE instructions which are then sent to
the SPEs for execution. Only a few opcodes work, no swizzling yet, no
support for constants/immediates, etc.

Do code generation for alpha test, z test, stencil, blend, colormask
and framebuffer/tile read/write as a single code block.
Ian's previous blend/z/stencil test code is still there but mostly disabled
and will be removed soon.

Fix incorrect opcode for fsmbi.
Added "macro" functions for loading floats/ints, register complement, zero, move.
Added #defines for return address and stack pointer registers.
Added assertions to check that the instruction buffer doesn't overflow.
